## 1) Build a huge image with all interpreters (default)
COPY --from=zeppelin-distribution /opt/zeppelin/interpreter ${ZEPPELIN_HOME}/interpreter
## 2) Build an image with only some interpreters
#### Copy interpreter-shaded JAR, needed for all interpreters
### COPY --from=zeppelin-distribution /opt/zeppelin/interpreter/zeppelin-interpreter-shaded-${VERSION}.jar ${ZEPPELIN_HOME}/interpreter/zeppelin-interpreter-shaded-${VERSION}.jar
#### Copy specific interpreters,  replace "${interpreter_name}" with your interpreter. Of course you can repeat the line with defferent interpreter
